LIanIn-nrsrnnsme APPARATUS.

Application filed. December 7, 1926. Serial No. 153,098.

' The present invention relates to a liquid dispensing apparatus and has for its principal object to provide a structure whereby liquid may be dispensed from the apparatus upon the depositing of a coin.

Another important object of the invention lies in the provision of a; coin controlled.

dispensing apparatus which will dispense a predetermined amount of fluid upon the insertion of a coin therein.

A still further very important object of the invention lies in the provision of a coin controlled mechanism which includes an esc'apement mechanism, operating control rods for the dispensing device, said escapeinent mechanism being set into operation by a trip releasable through the insertion of a coin into the apparatus.

.ii. still further very important object of the invention lies in the provision of an apparatus of this nature which is'comparatively simple in its construction, inexpensive to manufacture, not likely to easilybecome out of order, thoroughly eil'iCiBHt and reliable in its operation, and otherwise well adapted to the purpose for which it is de sigi'ied.

l Vith the above and numerous other ob-' je'cts in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts.

as will be hereinafter more fully described and claimed.

Fig. 5 is a detail perspective. view of a portion of the trip.

Referring to the drawing in detail, it will.

be seen that the numeral 5 denotes the casing'which has a lid 6 held thereon by a suitable lock 7 or in any other preferredmanner. A partition 8 divides the casing 5 up into a relatively large compartment A and a relatively small compartment 13. A measuring container 8 is located in the front bottom portion of the compartment A and has a pipe 9 leading rearwardly therefrom and atits rear end bent upwardly into a funnel valve seat i'n'ei'nber 10. A rod 11 has a ball valve 12 on the lower extremity there of which is adapted to seat into the member 1Q for cutting 01f the flow through the pipe 9. A lever 14 is pivoted intermediate its ends as at 15 on the upper edge of the partition 8 and the longer arm thereof extends" into the compartment A while the shorter arm thereof extendsinto the com-- pertinent B. The extremity of the long arm of the lever 14 is pivota'lly engaged with the rod 11 as at 16. A rod 17 is pivotally enga'ged at 18 with the extremity of the short arm of the lever 14 and extends downwardly into the compartment B where it is pivotally engaged with one end of a rocker 19 pivoted intermediate its ends at 20. A rod 21 has a lost motionconnection 22 with the other extremity of the rocker l9 and extends upwardly being pivotally engaged as at 23 with a rod 24 having a weight 25 adjustably mounted thereon. The rod 24 extends radially from a shaft 26 which is journaled inthe frame F. A second rod 27 extends radially from the shaft at an angle to therod 24,v preferably an acute angle, and is offset to one. side thereof and terminates in a lateral extension'29. A coin engaging plate 30 projects from the shaft 26 in a direction opposite to the rod 24 and is'located in'the path of the coin dropped through the coin chute 31 in the top or lidfi at the look end thereof. An escapement mocha nism E of. any. preferred construction is mounted in the frame F being operated by a vWindable spring S. This escapement. mechanism shown includes a plurality of meshing reducing gears having a wind-resistance element N in gear therewith. Such escapement mechanisms-are well known in the art andv need no detailed description here. A disk 33 is operated by the escapement mechanism E and this disk as is shown to advantage in Figure 4L is of an oblong rounded construction having notches 35 at opposite ends of its shorter axis. The periphery of the disk enters notches abruptly as at 35 to one side andgradually as at 86 to the other side. The extension 29 is adapted to ride on the periphery as shown in Figure 4, i

The spring F is maintained in a wound condition by a suitable key 37. A spigot 38 leads from the measuring container 8'. When the proper coin is dropped into the coin chute 31 it impinges on the coin engaging plate 30 and if of the proper denomination will overcome the balance of the adjustable weight 25 so as to rock the shaft 26 causing the lifting of the rod 21 to take up the lost play connection 22. The Weight of the coin will not be suflicient to rock the rocker 19 and the lever 14 to raise the valve 12 but will be sufficient to raise the extension 29 above the abrupt entrance 35 so as to ride on the sort of cam surface which is adjacent thereto and thus the spring operating the escapement mechanism-will cause'the turning of the disk 33 in the direction of the arrow in Figures 2 and 1 so that the rod 27 will further rock the shaft 26 and swing upwardly on the rod 24; so as to pull upwardly on the rod 21 and rock the rocker 19 pulling downwardly on the rod 17 and rocking the lever 14 to pull upwardly on the rod 11 to lift the valve'12. When the valve 12 is open it will be seen that the liquid in the compartment A will flow into the container 8 through the pipe 9 and the escapement mechanism will take sufficient time to turn the disk half a revolution so as to fill this container 8. When the disk has rotated a half revolution it. will be seen that the parts will automatically swing back into their original position because of the weight 25 and the weight ofthe valve 12, rod 11 and the longer arm of the lever 14.

It is thought that the construction, operation, and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merelyby way of example since in actual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description. It will be apparent that numerous changes in the details of construction and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its ad-' vantages. I

Having thus described my lnventlon what I claim as'new 1s:

1. A coin controlled apparatus of the class described including, in combination, an escapement mechanism includlng an oblong rounded disc having notches at opposite ends of the shorter diameter thereof, each notch having one abrupt approach and one gradual approach, a shaft, a rod extending from the shaft, a coin trip plate extending from the j 2. A coin controlled apparatus of the closs described including, in combination, an eseapeinent mechanism including an oblong rounded disc having notches at opposite ends of the shorter diameter thereof, each notch having one abrupt approach and onergradual approach, a shaft, a rod extending from the shaft, a coin trip plate extending from the shaft, a second rod extending from the shaft hav ng an extremity arranged to ride on the periphery of the disc, a third rod pivotally connected to the first rod, a valve, and a lever having means'to operate the valve and having a lost motion connectionwith the third rod, whereby the deposit of a coin upon the trip plate will release the escape ment mechanism "without operating the valve, said valve being operated by the rota-- tion of the oblong disc engaging the extension of the second rod, and a weight adjustably mounted on the first rod.

In testimony whereof I afiix my signature.
